On the other hand, the populations’ age pyramid, as well as their potential genetic traits and co-infections’ immuno-regulatory mechanisms could effectively decrease the infection’s severity. To lessen the direct and indirect impacts of the epidemic in these countries, it is crucial to strengthen their diagnostic and treatment capacities, using a thorough scientific analysis of local risk factors most likely to be improve our understanding of this pandemic.
